	Fixed up a display problem in the F1 menu in 256 color mode
	Fixed an echo delay bug
	Hopefully fixed the random beep encounter bug that occurs in some games with sound enabled
	Several sound volume fixes
	Sorry about those new problems in v0.941c. We traced some of the problems to the dos extender zsnes was using (thanks Maxim- for some help on this!) so we spent some time rewritng the file system so that it would be compatible with other extenders in pure dos.

	Rewrote 65816 flag handling system.
	Optimised SA-1 emulation
	Optimised the 65816 main loop.
	Implemented Surround Sound. It is defaulted off since it seem to create some bad static in some games. Thanks to Crono for info!
	Wrote Interpolation in MMX. MMX cpu is required.
	Implemented MMX auto-detection for MMX Interpolation and MMX Copy.

	Slightly fixed ADSR by completely skipping the attack stage when the attack duration is 0
	Fixed a GAIN decrease->increase bug
	Implemented a safe recovery feature for those computers that don't support the CPUID instruction (used for MMX detection). If ZSNES crashes at the very start, just re-run it.
	Fixed a fixed color dual windowing bug in the subscreen which caused transparency to sometimes shift unexpectedly when the background scrolls
	Implemented 50% Scanlines (Lance McKay's idea) and 25% Scanlines (Similar to Snes9x TV-Mode's scanline intensity) in 640x480x65536 video mode. These modes don't work on videocards with an ARGB setting yet.
	Added MMX Support to 50% and 25% Scanlines modes
	Implemented back buffer clear in MMX
	.CHT files now saves to the proper save directory
	Implemented the 2xSaI graphics engine (MMX Only). Many thanks to Kreed for this wonderful engine and source code!
	Implemented Kreed's Super Eagle engine. Note that for both 2xSaI and Super Eagle, you need an MMX processor, enough RAM for the new gfx 16bit engine, and also be in 640x480x65536 video mode.
	Implemented an option to auto-load a .cht file whenever a game is loaded. You can find this option at the bottom of the Cheat Window in the GUI.
	Optimised Non-MMX Interpolation
	Fixed a bug that caused save states to not save correctly after attempting to load a non-existing .cht file
	Added a Quick SnapShot Key. You can set this key in the Misc -> GameKeys menu in the GUI. This key allows you to take a snapshot with just a press of a key.
	Implemented .ZIP support. Thanks to Jean-loup Gailly, Mark Adler, and Gilles Vollant for the ZIP routines!
	Fixed a bug where pressing PageUp/PageDown in the cheat window went over by 3 entries.
	Implemented longer cheat descriptions. The cheat window and the .cht file format had to change a bit, however, ZSNES automatically converts any old formats to the new formats when it detects it.
	Allowed the IRQ to be executed more than once on the same line through HIRQ. Fixes the flickering problems of Doom/Offroad Baja.
	NMI now executes at line 225 instead of 224.
	Saving/Loading the state causing the control to stop or skip has been fixed again.
	.ZIP files can now be run from the commandline
	Implemented an option for ZSNES to automatically save the save data approx. 5 seconds after it detects writes to it. This will not work for SuperFX or SA-1 special chip games, however. This option is disabled by default and can be enabled through the option window.
	Implemented an option in the sound window to re-initialize the sound card after every 25-30 seconds. Hopefully fixes the problems where the sound gets staticy after a certain amount of time.
	Newest Save Slot will now appear as orange in the Save State Select (F3) window
	Fixed a spc700 65816 sync bug during movie (.ZMV) playback
	Implemented an option to enable Old Gfx Engine Mode 2 (Accessible through the options window in the GUI). This mode fixes many transparency problems in 16bit modes, but can also create some and is also at times slower than the original engine.
	Implemented 640x480x65536 VESA 1.2 support. Currently supports Full Scanlines and Smallscreen modes. However, it is strongly recommended that you only use VESA 1.2 support if your card cannot support VESA 2.0 (w/ linear framebuffer) since VESA 1.2 runs slower.
	Implemented an option to disable Pitch Modulation
	Sound card is now not re-initialized whenever a state is saved/loaded since some sound cards seems to have problems with it.
	Implemented Single Windowing in the New Gfx 8bit engine, 8x8 and 16x16 tile modes only
	Fixed 64k SRAM support when loaded from the GUI
	Optimised high resolution new gfx modes in 640x480x256

	Optimised 640x480x256 Eagle Engine
	Fixed the GUI background display bug in the new gfx engine
	Fixed .SPC capture in the new gfx engine
	Added an option to start with the newest save state when the game is loaded. It can be enabled in Config->Options window in the GUI
	Slightly optimised new gfx 8bit engine
	Fixed several Mode 7 problems in the New Gfx 8bit engine
	Changed DSP1 variables to use double instead of floats for a small speed increase. Thanks to Gary Henderson for this tip!
	Fixed up the Mode 7 slowdown bug when the scale ratio becomes small in most graphics modes
	Optimised some Mode 7 transparency modes
	Implemented EXTBG mode 7 into the newgfx 8bit engine
	Fixed the 'FIX' feature in the cheat menu. Seems like it wasn't writing any value to memory when it was clicked.
	Game Genie codes are now defaulted to the 'FIX'ed mode. Seems like most of the codes needs this.
	Implemented windowing to Mode 7, New Gfx Engine 8bit
	Added support for .SPC v0.2 format
	Added an option in zsnes.cfg to disable configuration saving for those who want to store zsnes.exe in a read-only storage area
	Fixed GameKeys display in the GUI for certain keys (such as the snes parallel adapter keys)
	Implemented hi-res mode 7 (vertical expand only). Currently only works in 640x480x256 newgfx engine (w/ Eagle and Scanlines disabled).
	Fixed an offset per tile mode bug in the new gfx 8bit engine
	Implemented dual windowing modes into the new gfx 8bit engine
	New Gfx 8bit engine is now the default graphics engine in 256 color modes. It still lacks sprite windowing and also has some sprite flicker issues, but it's overall more stable, faster, and has more features. You can still switch back to the old gfx engine by pressing '8'.
	Looks like Pitch Modulation was causing more sound problems than what it's worth. It's now disabled by default, but you can reenable it through the GUI.
	Added auto save/load state feature where ZSNES will automatically loads back the previous state when you last properly exited ZSNES. This feature is disabled by default.
	Compressed the executable using UPX

	Fixed up sound speeds. Timers were computed incorrectly.
	Fixed a sprite priority bug
	Fixed up a bug that prevented the gui to be disabled
	Fixed up SPC capture
	Fixed a bug when VIRQ is set on the same scanline as NMI
	Implemented an automatic .IPS patcher. Just rename your .IPS file to the rom filename with the .IPS extension and ZSNES will patch the rom realtime without modifying the rom file's contents. Thanks to Neill Corlett for most of the .IPS info!
	Snapshot capture/skip 2 frames option now returns back to the proper menu item
	Fixed a calibration bug with 6/8button joysticks

	Fixed up echo emulation (possibly slowed down emulation)
	Fixed up a sprite caching bug
	Fixed up a DSP1 byte check stall bug
	Implemented a commandline to disable spc700 speed hacks (-7) Might help with some compatibility
	Implemented SA-1 support (most functions emulated)! Unfortunately, it's still buggy. Thanks to the snes9x team for providing info!
	Fixed a bug when selecting drive A/B while a disk is not in the drive caused a long check sequence
	Implemented Keyboard support to most of Option, Sound, and GUI Option configurations in the GUI
	Changed sound init code a bit. Hopefully improves sound card compatibility, but might also ruin it.
	Implemented off by 1 line fix (-9). This may help compatibility and fix some minor graphic glitches, but may also ruin some too.

The following things were added in ZSNES v0.715c:

	Fixed a crashing bug when 16bit back window clipping was using an undefined windowing clip buffer
	Added spc program counter check to the spc stall detection to reduce false alarms
	Tweaked IRQ processing a bit
	ZSNES.CFG and ZGUICFG.DAT are now fixed so that they will use the current directory when the SET CMDLINE detection fails

	Fixed up a bug where any memory allocation below 48mbit support crashes
	Added out of memory error when loading a file from the gui
	Fixed a minor off by 1 pixel windowing bug
	Fixed up memory requirements in the readme.txt. It seems like compiling with C takes up 3.0 more megs. It shouldn't though. An asm only version will be release later without dsp1/ipx support unless the reason is figured out.

The following things were added in ZSNES v0.700c:

	Fixed another offset per tile mode bug
	Fixed up joystick button update rate
	Fixed a bug that caused sound buffer dump option to crash
	Fixed a minor sound initialization bug
	ZSNES now compiles with C code!
	Fully rewritten commandline parser routines

	Implemented snapshot/increment by 2 frame feature in the F1 menu for those interested in producing animations
	Added variable sound buffer size to reduce static in higher sampling rates
	Changed method of reading the mouse cursor position in the GUI. Hopefully, this fixes those mouse crash problems when zsnes is run in pure dos and sometimes win95.
	Added a commandline to disable palette 0 (back color) modification in 256 color modes
	Implemented Turbo Buttons for buttons A,B,X, and Y. Use the GUI to define those keys
	Added the ability to toggle Turbo Change speed to 30hz instead of 60hz in the Options menu
	Started C4 chip emulation. Nothing is playable yet.
	Fixed up SET CMDLINE detection. Hopefully, zsnes.cfg and zguicfg.dat will now end up in the correct directory.
	Started Modem Support (direct modem to modem). DOS-Compatible modem required! Thanks to Dark Force for helping out on getting a bug that kept USR's and other modems from working! Also thanks to The Minder for a lot of help testing! Note : Modem mode isn't free of bugs
	Added in-game chat key to the GUI keys for modem/net support. Currently defaulted to 't'
	Forgot to add EMMS after any MMX routines that seems to cause any FPU instructions to crash
	Fixed an interrupt re-enable bug in the Gamdpad Pro code which seems to have eliminated the locking bugs when it's not set on GrIP mode
	Implemented keys to adjust Frame Rate up or down during gameplay. You can define them through the GUI under Gamekeys
	Implemented keys to slide the volume level up or down during gameplay
	Fixed a small HDMA screw up bug when using Save/Load states which caused the screen to flicker once in many games
	Finally fix up 48mbit mapper support! Many thanks to Dark Force, Mike Gilroy, and Frank Hughes for a lot of help on this!
	Several fixes to register 4211h
	Rewrote IRQ timing handler (not perfect, but better)
